OO grease is available from Tractor Supply and will perform as
105 and Corn head grease. 105 and Corn head grease are an O
grease, one grade thicker. The fit of the shafts and bushings
after 80 – 90 or 100+ years determines how long you can go
before you need to add more grease. When I tried using this OO
grease it was gone rather quickly. I tend to still use my motors
and may run them for weeks at a time. The O grease “seems” to
extends the time as to when I need to remove the motor to add
more grease. That needed to be done a few tanks of gas earlier in
the picture above. Of the 3, I prefer 105. This is my experience.
Your experience will determine which lubricant is best for you.
